The MetaRock Laboratories, Inc. Autosampler (MRAS) is an automated high-performance sample collection solution suited for a wide variety of applications. The MRAS is controlled through an intuitive and user-friendly PC- based software application, while also allowing for use in a simple time-based manual mode.

Standard wetted materials are: 316 stainless steel for flow lines, and glass for collection vials which ensure compatibility with a variety of fluids. Hastelloy, Titanium, Monel, Teflon and other materials are available for applications with extremely reactive or corrosive materials. The MRAS utilizes pneumatic actuators and low voltage DC controls to minimize associated risks with the collection of flammable or combustible fluids and gases.

The autosampler consists of a 24 position rotor controlled by a precision indexing pneumatic actuator with a non-accumulating error of +/- 0.1 degree per 15 degree step; and a pneumatically actuated dual-needle probe to penetrate the septum sealed sample vial. The dual needle probe design provides a means for continuous measurement of gas production rates and volumes when connected to external measurement devices such as the MRL Flow Qube syringe pumps or Thermal Mass Flow Meters.

Up to 24 sample vials can be loaded at any given time, while filled sample vials can be quickly and easily replaced with empty ones at any time allowing for an unlimited number of samples to be taken. Standard calibrated sample vials are available in 10ml and 25ml sizes; however, custom sizes can be provided for customer specifications as needed.
